The object of this invention is to provide a novelty in connection with an advertising display device, and is intended particularly for use in connection with advertisements relating to lubricating oils. The invention provides a mechanically operated device so constructed and operated as to be illustrative of the Well known test for lubricating oils, practiced by mechanicians, in which a drop of oil is .placed between the thumb and fore-finger of the hand, and by the sense of touch, one gauges the body or lubricating value of the oil to be tested. In such a test, and with the drop of oil between the finger ends, the fingers are moved slightly toward and away from each other in order to get the benefit of the sense of touch which is or may be highly developed in the finger tips. In separating the fingers, the drop of oil assumes asomewhat attenuated torm or outline; and it is the further object of this invention to represent, as accurately as possible, the changing outline of the oil drop as the fingers are separated.

Other objects of the invention will be apparent from the following description of the invention that is made with reference to the accompanying sheet of drawing which forms a part of this application.

Referring to the drawing,

Fig. 1 is a side elevation of a practical embodiment of our invention; and

Fig. 2 is a detail View, partly in section, showing the finger parts of the apparatus in, whatmay be termed, the closed position.

A figure in representation of a hand. is shown at 1. This figure may be made of molded plastic material, or may be cut from suitable fiat material such as'lumber, composition board, or the like. In using the latter material, it is preferable that stock of such thickness be employed as will show adequate finger thickness in order to present a natural appearance, and also to afford proper support for certain elements of thestructure I which are associated with the finger tip-s and which will be hereinafter described.

In the use of this device for display purposes, it is'not essential that a complete hand shall be visible in the display, since it is only the fingers of the hand that are important,

the hand.

mit Q m eme e een theifiesers is i show an electric motor M with a worm and worm wheel drive, and an angularly disposed connecting rod between a wrist pin on the worm wheel and the hingepin o'fthe forefinger, which latter pin is fast with the finger structure, andhas a hearing or bearings in This specific form of drive is chosen to illustrate an operative mechanism capable of producing the slow-motion finger movements desired. It will be obvious that other mechanical elements might be chosen to serve the same purpose. I 1

Nearthe outer .end of the fore-finger a bulbous enlargement or projection 5 is pro vided which is recessed to receive a socket element 6. The thumb is provided with an upstanding projection 7 the upper endof which is substantially cylindrical, and dimensioned to slide relative to and within the recess 6. The base of the projection 7 on the thumb is flaring to represent, in outline, the spread of an oil drop that is held between the fingers.

In operation, the motor being supplied with energy, the finger'3 will be slowly moved about the pivotal point l, and the finger tips will appear to be moved toward and away from each other, with the upper end of the nm e a l s di s' a erially t in h recess 6 of the upper pro ection. lower trated in F 1g. 2, where the pro ect on 7 subten y fi l he ;136@Q$ I th l mi f p a issms emei b ween the fingers-th upper end of the projection 7 remains somewhat within'the recessfi in order to avoid the appearance of a break in the drop of oil under test. By proper shaping of the projections 5 and 7, and control of the finger movement-s it'is possible to closely simulate the actual appearance of a drop of oil as it is tested for body in the common-place finger test as 1 practiced b mechanics.

In use 0 this invention for display purposes, as in the window of a store or service- 5 station, the device may be positioned behind a screen or display card, with the fingers showing through an opening in the screen or 'card, and an appropriate size of opening is suggested by the circle, in broken line 8, shown m in ig. 1. The purpose of this accessory, obviously, is to screen or obscure from view the operative parts of the device including the motor and its drive connections.

Having described our invention, what we claim as novel is:

1. In an advertising display device opera- -tiv'e to simulate the known method of testing with the fingers the body of lubricating oils, comprising a figure shaped in representation m0 of a hand with the thumb and fore-finger horizontally extended, cooperating parts secured to the thumb and finger adjacent their outer ends, and means for producing a limited relative movement of the finger and thumb toward and away from each other whereby the said cooperating parts are moved to produce the effect of finger testing a drop of oil.

2. In an advertising display device operative to simulate the known method of testing 30 with the fingers the body of lubricatingnils. comprisin a figure shaped in representation of a. hen with the thumb and fore-finger horizontally extended, cooperating parts secured to the thumb and finger adjacent their outer ends comprising telescoping projections, and means for producing a limited. relative movement-of the finger and thumb to ward and away from each other whereby the said cooperating parts are moved to produce the effect of finger testing a drop of oil.

3. In an advertising display device operative to simulate the known method of testing with the fingers the body of lubricating oils, comprising a fi ure shaped in representation of a hand with the thumb and forefinger V horizontally extended, cooperating parts se cared to the thumb andv finger adjacent their outer ends comprising telescoping projections so shaped that their outline in coopera- Tm tive positions resembles the outline of a drop of oil held between finger tips, and means for roducin I a limited relative movement of the nger an thumb toward and away from each other whereby the said cooperating parts are moved to produce the effect of finger testing a drop of oil. 7 In witness whereof we have hereunto set our hands this 19th day of November, 1929.
